Find the best dates for planting vegetables and fruit in your garden! Our free planting calendar calculates the best time to start seeds indoors and outdoors, as well as when to plant young plants outside.

How to Use the Planting Calendar

Simply put, a planting calendar is a guide that tells you the best time to start planting your garden. Most planting calendars are based on frost dates, which dictate when you should start seeds and when it's safe to plant outdoors in your area. Our planting calendar is customized to your location in order to give you the most accurate information possible.

On the planting calendar below, please note:

  • The Frost Dates indicate the best planting dates based on your local average frost dates. Average frost dates are based on historical weather data and are the planting guideline used by most gardeners.
  • The Moon Dates indicate the best planting dates based on your local frost dates and Moon phases. Planting by the Moon is considered a more traditional technique.
  • The Plant Seedlings or Transplants dates indicate the best time to plant young plants outdoors. This includes plants grown from seed at home and plants bought from a nursery. Although frost dates are a good way to know approximately when to start gardening, always check a local forecast before planting outdoors!
  • When no dates ("N/A") appear in the chart, that starting method is typically not recommended for that particular plant, although it likely still possible. See each plant's Growing Guide for more specific information. Some crops do best when started directly in the garden, while others are best started indoors and transplanted outdoors later on. Your climate and the length of your growing season are big factors in determining what to start indoors and outdoors.

To plan your garden more accurately in the future, keep a record of your garden's conditions each year, including frost dates and seed-starting dates!
